Subject: [xsl] Printing CDATA from feed as HTML

Using xsl 1.0 with php 5.x

I'm trying to consume an atom feed and I'd like to print out the full body of the content. It's wrapped in a CDATA section so I'm having trouble getting it to display correctly. The tags come out escaped despite adding the disable-output-escaping. I've looked via google and not found an answer.

Sites do this so it must be possible somehow. Right? Snippets below
Links to a manual to read are fine too.

Thanks!
Joelle

My XML snippet (Typical atom feed I'm guessing?) full feed at http://blog.lib.umn.edu/huntx010/ici/atom.xml:

My xsl snippet:

   <xsl:template match="atom:entry[position() = 1]">
       <h3>
           <xsl:apply-templates select="atom:title"/>
           <xsl:text>
           </xsl:text>
           <span class="feed_posted">Posted on:
               <xsl:apply-templates select="atom:updated"/></span>
       </h3>
      <xsl:value-of disable-output-escapting="yes" select="atom:content"/>
   </xsl:template>

It generates:

<h3><a href="http://blog.lib.umn.edu/huntx010/ici/2008/06/further_reflections_on_green_l.html">(Further) Reflections on Green Living</a>
<span class="feed_posted">Posted on: 06/11/2008</span></h3>

I want (We'll I'd really like to strip out the <br /> tags, but I think I can do that. The part I'm struggling with is the escaping):

I think one thing that needs to be cleared up is "Is the pseudo-markup in the CDATA section guaranteed to be xhtml as opposed to html?", it appears to me that it might not be XML so parsing it might fail.
